2020-12-10hw/intc/armv7m_nvic: Implement read/write for RAS register blockPeter Maydell
The RAS feature has a block of memory-mapped registers at offset 0x5000 within the PPB. For a "minimal RAS" implementation we provide no error records and so the only registers that exist in the block are ERRIIDR and ERRDEVID. The "RAZ/WI for privileged, BusFault for nonprivileged" behaviour of the "nvic-default" region is actually valid for minimal-RAS, so the main benefit of providing an explicit implementation of the register block is more accurate LOG_UNIMP messages, and a framework for where we could add a real RAS implementation later if necessary.

2020-12-10hw/intc/armv7m_nvic: Make all of system PPB range be RAZWI/BusFaultPeter Maydell
For M-profile CPUs, the range from 0xe0000000 to 0xe00fffff is the Private Peripheral Bus range, which includes all of the memory mapped devices and registers that are part of the CPU itself, including the NVIC, systick timer, and debug and trace components like the Data Watchpoint and Trace unit (DWT). Within this large region, the range 0xe000e000 to 0xe000efff is the System Control Space (NVIC, system registers, systick) and 0xe002e000 to 0exe002efff is its Non-secure alias. The architecture is clear that within the SCS unimplemented registers should be RES0 for privileged accesses and generate BusFault for unprivileged accesses, and we currently implement this. It is less clear about how to handle accesses to unimplemented regions of the wider PPB. Unprivileged accesses should definitely cause BusFaults (R_DQQS), but the behaviour of privileged accesses is not given as a general rule. However, the register definitions of individual registers for components like the DWT all state that they are RES0 if the relevant component is not implemented, so the simplest way to provide that is to provide RAZ/WI for the whole range for privileged accesses. (The v7M Arm ARM does say that reserved registers should be UNK/SBZP.) Expand the container MemoryRegion that the NVIC exposes so that it covers the whole PPB space. This means: * moving the address that the ARMV7M device maps it to down by 0xe000 bytes * moving the off and the offsets within the container of all the subregions forward by 0xe000 bytes * adding a new default MemoryRegion that covers the whole container at a lower priority than anything else and which provides the RAZWI/BusFault behaviour Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20201119215617.29887-2-peter.maydell@linaro.org

Support for migration of vfio devices is still in flux. Developers are attempting to add support for new devices and new architectures, but none are yet readily available for validation. We have concerns whether we're transferring device resources at the right point in the migration, whether we're guaranteeing that updates during pre-copy are migrated, and whether we can provide bit-stream compatibility should any of this change. Even the question of whether devices should participate in dirty page tracking during pre-copy seems contentious. In short, migration support has not had enough soak time and it feels premature to mark it as supported. Create an experimental option such that we can continue to develop.

2020-11-18s390x/pci: fix endianness issuesCornelia Huck
The zPCI group and function structures are big endian. However, we do not consistently store them as big endian locally, and are missing some conversions. Let's just store the structures as host endian instead and convert to big endian when actually handling the instructions retrieving the data. Also fix the layout of ClpReqQueryPciGrp: g is actually only 8 bit. This also fixes accesses on little endian hosts, and makes accesses on big endian hosts consistent.

2020-11-13intc/ibex_plic: Ensure we don't loose interruptsAlistair Francis
If an interrupt occurs between when we claim and complete an interrupt we currently drop the interrupt in ibex_plic_irqs_set_pending(). This somewhat matches hardware that also ignore the interrupt between the claim and complete process. In the case of hardware though the physical interrupt line will still be asserted after we have completed the interrupt. This means we will still act on the interrupt after the complete process. In QEMU we don't and instead we drop the interrupt as it is never recorded. This patch changed the behaviour of the Ibex PLIC so that we save all interrupts that occur while we are between claiming and completing an interrupt so that we can act on them after the completition process. This fixes interrupts being dropped when running Tock on OpenTitain in QEMU.
